# NVIDIA Fabric Manager

> In this guide we'll follow the procedure to enable NVIDIA Fabric Manager.

NVIDIA GPUs that have nvlink support (for eg: A100) will need the [nvidia-fabricmanager](https://github.com/siderolabs/extensions/pkgs/container/nvidia-fabricmanager-lts) system extension also enabled in addition to the [NVIDIA drivers](https://docs.siderolabs.com/talos/v1.15/configure-your-talos-cluster/hardware-and-drivers/nvidia-gpu.md).
For more information on Fabric Manager refer [https://docs.nvidia.com/datacenter/tesla/fabric-manager-user-guide/index.html](https://docs.nvidia.com/datacenter/tesla/fabric-manager-user-guide/index.html)

The published versions of the NVIDIA fabricmanager system extension are listed on the [`nvidia-fabricmanager-lts` package page](https://github.com/siderolabs/extensions/pkgs/container/nvidia-fabricmanager-lts).

> The `nvidia-fabricmanager` extension version has to match with the NVIDIA driver version in use.

## Enabling the NVIDIA fabricmanager system extension

Create the [boot assets](https://docs.siderolabs.com/talos/v1.15/platform-specific-installations/boot-assets.md) or a custom installer and perform a machine upgrade which include the following system extensions:


  ghcr.io/siderolabs/nvidia-open-gpu-kernel-modules-lts:580.196.07-v1.15.0-beta.0
  ghcr.io/siderolabs/nvidia-container-toolkit-lts:580.196.07
  ghcr.io/siderolabs/nvidia-fabricmanager-lts:580.196.07

  

Patch the machine configuration to load the required modules:

```yaml theme={null}
apiVersion: v1alpha1
kind: KernelModuleConfig
name: nvidia
---
apiVersion: v1alpha1
kind: KernelModuleConfig
name: nvidia_uvm
---
apiVersion: v1alpha1
kind: KernelModuleConfig
name: nvidia_drm
